A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I have both a business and personal subscription to Office 365. Since I use my machine primarily for personal use, I have the default account set to that. When I got this message, I switched to the business account and it worked fine. I assume, then, that this is a licensing issue related to personal accounts.
Did Microsoft make a licensing change or is this a configuration issue?
